A ‘mock-up’ is a copy of the flat artwork design in full colour, presented so that, following cutting and folding where necessary, it provides a replica of both the outer and immediate packaging so that the three dimensional presentation of the label text is clear. It is generally referred to as a "paper copy" or "computer generated version". Mock-ups may be submitted in full size hard copy and in colour or electronically.

Mock-ups are requested for initial applications and on a case-by-case basis for other procedures with major impact on the labelling, e.g. variations, renewals, extensions.

Due to the different nature of the veterinary medicines domain, the Agency will continue, as in the past to check mock-ups rather than specimens but, similarly as for the Human domain, will only review layout, legibility etc. The obligation to ensure that the final packaging exactly mirrors the approved mock-ups rests with the Marketing Authorisation Holder.
